How to Remove Rust Stains From Tub

Although this is not our area of expertise, we thought we'd pass on this information that was tested by our employees. They are always talking about their own home repairs and we thought this was an interesting topic and solution.
Rust in the bathroom is usually the result of two related situations. Either iron-containing metals in your bathroom fixtures have begun to rust OR your mineral-rich water supply contains iron particles and has begun to stain areas where water runs. This happens even with a porcelain tub as two of our employees found out.
Bleach and Tilex made the rust stains worse and they sparked another chemical reaction, creating more rust stains on the non-skid surface on the tub floor. Other products that either made things worse or didn't work at all: Lysol, toilet bowl cleansers, Soft Scrub, Goof Off, Awesome, Comet, Simple Green, Mean Green, Magic Eraser and CLR,
However, we found 2 things that really worked: Clorox2 and Hydrogen Peroxide. The Clorox2 worked best and required less scrubbing. Just pour either product on the stain and let it sit. Then scour gently with a damp sponge and rinse. If the stains are really bad you may have to repeat the process twice.

    Would Clorox2 and Peroxide work on Kitchen Porcelain sinks

      Spray it with a mixture of 1 part cleaning vinegar & 1 part Dawn. Let it sit for 10-15 minutes then scrub it and rinse. It might take 2 rounds of this but it works! We have a fiberglass tub/shower surround that no matter how hard I scrubbed, I couldn't get the soap scum all off and this mixture worked like a dream!

    "Iron Out" from walmart is amazing (use it in your white laundry also for super white with no yellowing!) but it is a bit pricey; going to have to try this

    I used Iron Out initially on the rust in our shower. We had really high iron content in the water. A new system was put in and we don't see the color in the water any more but it does still exist. The Iron Out got out the orange color but the tile and grout are still darker than they were. If you use the Clorox2 and Peroxide do you mix them....they always say not to mix chemicals?

    Use Lysol Rust & Lime toilet bowl cleaner & the rust will "melt away" on contact with no scrubbing necessary just wipe it around with a rag or something slightly abrasive if you prefer. I'll never use anything other than the toilet bowl cleaner ever again, but it HAS to be the Lime/Rust version in the black bottle.
